Well, it's 20EURO here for a game I wasn't so fond of by playing the demo. It seemed quite repetitive and it's a pure single player game - one playthrough and you're pretty much done. Achievements and stuff like that - not my thing. I know the game is good and a lot of work went into it, but I can't justify paying 20EURO (16 work hours for me) for a 6-10 hour experience.
Which is why I never pay for sex too - 10 minutes of fun, 3 days of work
